Primary objectives of the project ‘Sustaining the Productivity of Tree Crops on Agricultural Land in South-Western Australia’ were to quantify the changes to the fertility of agricultural soils planted to eucalypts and to evaluate strategies to maintain soil fertility and sustain long-term plantation productivity.
The project team addressed the objectives using two approaches. The first evaluated changes to nutrient forms and fluxes in surface soils at paired pasture-plantation sites covering the area in which E. globulus has been planted in south-western Australia. The second approach examined the effects of inter-rotation site management treatments on soil nutrients in experiments at two sites.
